This week marks the tenth anniversary of the Oso landslide. On March 22nd 2014, a wall of mud and debris rushing 60 miles an hour hit the neighborhood of Steelhead Haven, near the North Fork of the Stillaguamish river along Highway 530. 43 people were killed. It remains the deadliest landslide in US history.We can only make Soundside because listeners support us. Make the show happen by making a gift to KUOW:https://www.kuow.org/donate/soundside
